Abstract: A device and a method wind a thread on a winding machine. The winding machine has a spool sleeve and a spool holder, which has two oppositely disposed centering plates, having an adjustable axial distance relative to each other, for tensioning the spool sleeve. The centering plates each have a centering cone which engages in an open spool sleeve end, and an arrester hook for arresting the thread being provided in one of the centering plates. The arrester hook is oriented in the circumferential direction of the centering plate, and the centering plate having the arrester hook contains an outer cone which overlaps the outer diameter of the spool sleeve end. An inside of the arrester hook is formed by a nose-like recess provided in the outer cone.

Abstract: Techniques involve extruding, orienting and winding up a skein of film tapes or monofilaments. In particular, an apparatus has an extrusion installation, a plurality of drawing-off rollers and orienting rollers and a multiplicity of winding positions which are held alongside one another and one above another on an operating side of a frame wall. The winding positions are configured such that the wound packages are kept ready for removal at the frame wall on a doffing side on the opposite side from the operating side. Such an apparatus is able to achieve a material flow that is as continuous as possible during the production of the film strips and monofilaments.

Abstract: A projectile with a projectile casing and at least one pyrotechnic charge incorporated in the projectile casing is proposed, wherein the projectile has an open projectile base with a destructible membrane and the pyrotechnic charge burns away at a defined rate during the flight of the projectile, and so the projectile loses mass in such a way that a predetermined effective range is not exceeded. As a result, safety and a nonlethal effect are achieved, in particular outside the effective range.

Abstract: A protection and defence system for an infrastructure against a threat approaching the infrastructure, comprising at least one effector. When a threat is determined, the at least one effector dispenses a non-lethal countermeasure which damages the threat and thus causes its crash. Vision and target tracker, such as at least a camera and tracker, and at least one directing/actuating drive are allocated to the effector or effectors. The effector and the vision and target tracker thereof are supported by a modular platform which can be fixedly installed to/on various infrastructures, can be removed therefrom and be used in a mobile mode. In addition, the platforms comprise a sensor that detects the spatial position of the effectors.

Abstract: A pelletizing press for producing pellets from material to be pressed, preferably from biomass, for use as fuel in fire places, wherein the biomass consists of cellulosic and/or lignocellulosic fibers, chips or shreds. In the pelletizing press, a dispersion chamber is formed by at least one die having a plurality of bores for pressing the biomass and at least by a lateral wall, and at least one roller rolling on a rolling surface of the die is arranged in the dispersion chamber. A pelletizing press of this method for producing pellets enables the formation of a dispersion chamber that, by means of at least one lateral wall, is as compact and sealed as possible relative to the prior art. At least two lateral wall parts are arranged to form a lateral wall; at least the first lateral wall part is arranged to be movable in relation to the second lateral wall part for carrying out a relative movement.

Abstract: A pellet press for producing pellets from material which is to be compressed. In the pellet press, the biomass is compressed through the holes of the die by at least one press device comprising a roller which rolls on the die, to form pellets. The die and/or the roller move in relation to each other during the production thereof. Provides essential machine elements or modules which are simple to access and also quick to exchange. The construction and operation of the pellet press should be modular so that the production power can be variably adjusted and/or the production is independent of the repairs of individual modules. At least one press device comprising at least one roller and/or the die is arranged inside a press frame in the pellet press, the press frame being embodied in the form of at least one C-frame and/or at least one window frame.

Abstract: A pelletizing press for producing pellets, preferably from biomass, for use as fuel in fireplaces, includes at least one die having a plurality of bores for pressing the biomass, at least one roll rolling on a rolling surface of the die, and at least one drive device for the die and/or the roll. The pelletizing press makes it possible to use a die having as low a height as possible, and thus as short a bore length as possible. For mounting the die, a carrier plate seated in a substantially planar manner against the die is arranged downstream of the die in the passage direction of the biomass. At least one opening for releasing the bores of the die is arranged in the carrier plate.

Abstract: The invention relates to a method and an apparatus for producing a turf yarn for artificial turf. According to the invention, several monofilaments or ribbons are produced from one respective polymer material in two parallel extrusion processes, the turf yarn being formed by combining several monofilaments or ribbons obtained in the first extrusion process with several monofilaments or ribbons obtained in the second extrusion process. In order to improve especially the elasticity of an artificial turf carpet made from said turf yarn, the monofilaments or ribbons obtained in one of the extrusion processes are crimped before being combined, the crimped monofilaments or ribbons and the flat monofilaments or ribbons being produced in parallel next to each other and being joined in a winding station by means of a tie thread.

Abstract: The invention relates to a method and a device for producing a grass yarn for artificial turf. A film is produced from a polymer material in an extrusion process and divided into individual strips. The strips are crimped before being coiled into spools. The aim of the invention is to achieve a structure which particularly matches natural grass. According to the invention, this is achieved in that the film or the strips are fibrillated by a needle roller before crimping and the strips are separated after on and individually crimped independently of each other.
